(9/2)/(54/7) = (9/2)x(7/54) = (63/108) = 21/36 = 7/12
Divide numerator and denominator by 9: 99/54 = (11×9)/(6×9) = 11/6
54
6/7 x 9/9 = 54/63 80/9 x 7/7 = 560/63 54/63 + 560/63 = 614/63
7/9-2/3=7/9-6/9=1/9 remember to use the least common denominator.
(9/2)/(54/7) = (9/2)x(7/54) = (63/108) = 21/36 = 7/12
